ELECTRIC VULCANIZER.

Specification of Letters Patent.

Patented Jan. 17, 1911.

Application filed-SeptemberlfiZ, 1907. Serial No.'392,456.

To all whom it may concern:

Be it known that we, \VAL'rnn C. FISH and ARTHUR M. STANLEY, citizens of the United States, residing at Lynn, county of Essex, State of Massachusetts, have invented certain new and useful Improvements in Electric V ulcanizers, of which the following is a specification.

This invention relates to devices for vulcanizing tires, and has for its object the provision of means whereby the tire may be -.vulcanized, either in whole or inpart, by

the application of an' reliable, safe and efficient manner.

In carrying out our invention, we provide a casing having a heat-conducting surface adapted to be brought into good thermal relation with the tire. This casingis preferably made sons to entirely inclose the tire, and as a matterof convenience in applying the same, is made-in sections. A plurality of heating units are mounted around the casing in good thermal relation to the casing, the units being prefe'fitbly of the self-contained removable type, the connections being such that any number of units may be included in the circuit at one time so thatjeither' the whole or part of the tire may be heated as desired.

In the accompanying drawings, in which we have shown our invention embodied in a concrete form, Figure l is a view of the tire having my device applied thereto, certain of the parts being broken away; Fig. is a partial section of the casing; and Fig. 3 is a fragmentary view of the tire showing the details ofthe casing and connections of the heating units. Referring to the drawings, lis a' pneumatic tire for use on automobiles and the,

like, having a rubber tread which it is de-' sired to vulcanize. erably made entirely of metal, is formed in two sections, 2 and 3, pivoted together at 4 and having a clamping bolt 5 pivoted at 6 in section 3 and adaptedto engage a yoke 7 in section 2, so that by screwing up thenut 8, the casing can be brought into good heat conductive relation to the tire. Theinner side of the casing is made to conform to, the shape of the tire, as'shown in Fig. 2, and a plurality of holes or pockets 1 are formed around the casing in'close proximity to the tire. These pockets are adapted to receiveheating units 10. v

electric current in a A circular casing, pref-' clamped over the ti're.

The units are theuconnected to-- LYNN, MASSACHUSETTS, ASSIGNORS I the units are all connected in series, whereas if only a portion the heating units adjacent-said portion may be energized and the others disconnected. lVhenit is desired to /repair ,thetire, as for instance to apply a tire tread thereto, a strip of rubber-13, impregnated with sulfur, is placed around the tire and the casing is The current is then turned on and the casing is brought up to the temperature to cause vulcanization. The temperature'may be taken at points around the' tire by-pla'cing a thermometer in the holes 14. It will be seen therefore of the tire is to be heated,

that a uniform temperature may be applied to'. a'tire in a very simple manner, and that little or no experience or skill is required.v

The device is so proportioned and arranged that the casing will be brought up to a defi; j

nite temperature simply turned on zation is complete.

It Will be understood, of COLlISt-Zfytllfili' various modifications will suggest themselves to those skilled in the of which is set forth in the annexed claims."

What we cl-aim as new and desirelto se-" cure by is, p

1. A- tire vulcanizer comprising a sectional- "casi-ngand a plurality of self-com tamed heating units mounted at intervals around said sections.

and the current can be" and left until the vulcani- 9 I art without departi tgfrom the spirit of. our 'invention tlrejscope' Letters Patent of the United State's,

2. A tire vulcanizer comprising a; circular casing composed of segmental sections and a plurality of heating units mounted--at intervals around the circumference 'of said casing. e

' 3. A tire vulcanizer comprising a circular casing composed of semi-circular' sections and a plurality of heating units mountedat units intervals around the circumference of said casing.

4. A tire vulcanizer comprising a circular easing composed of semi-circular sections pivoted together and a plurality of heating mounted at intervals around said casin 5.-A tire vulcanizer comprising a casing composed of semi-circular sections pivoted together, a plurality of self-contained heating units mounted at intervals around said casing, and connections whereby any number of said units may be heated as desired.

6. A tire vulcanizer comprising a sectional casing, a plurality of self-contained heating units mounted at intervals around each section and connections for heating of said units as desired. I

7. A tire vulcanizer comprising a casing composed of segmental sections, a plurality 2 of self-continued heating units mounted at intervals around each sectionv and connections whereby any number 01'' said units may be heated as desired.

In witness whereof, \YO have hereunto set our hands this ninth day of Septc1nber,l90T.
